Application filed April 17, 1919. Serial No. 290,739.

T 0 all whom it may concern:

Be it known that I, EDWARD A. F InLD, J r., citizen of the UnitedStates, residing at Oak ark, county of Cook, State of Illinois, haveinvented certain new and useful Improvements in Governors, of which thefol lowing is a specification.

This invention relates to improvements in governors.

My improved governor is especially desi ned by me as a governor forinternal combustion engines, although certain features are desirable foruse in other relations.

The main object of this invention is to provide an improved governor forinternal combustion engines which is sensitive and accurate in itscontrol and at the same time one which is durable and compact instructure.

Further objects, and objects relating to structural details, willdefinitely appear from'the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification. The invention is clearlydefined and"pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing. forming a part of thisspecification. in which:

Figure I is a plan view of an intemal combustion engine embodying thefeatures of my invention.

ig. II is a detail end elevation of the structure shown in Fig. I.

Fig. III is a detail view of the governor parts with the housing mainlybroken away.

Fig. IV is a detail section on a line corresponding to line 4:4 of Fig.III.

Fig. V is a detail vertical section on a line corresponding to line 55of Figs. I, II. III and IV.

Fig. VI is a detail vertical section on a line corresponding to line 66of Figs. I, IV and V.

Fig. VII is a detail section on a line corresponding to line 77 of Figs.IV and V.

Fig. VIII is a detail vertical section on a line corresponding to line8-8 of Figs. I and IX, showing a housing for the valve connecting linkand valve connection.

Fig. IX is a detail section on a line cor- 17 closing ppppiinding toline 9-9 of Figs. II, III and In the drawing similar referencecharacters refer to similar parts throughout the several views, and thesectional lines are taken looking in the direction of the little arrowsat the ends of the section lines.

Referring to the drawing, 1 represents the body of an internalcombustion engine havmg horizontally disposed opposed cylinders. As thedetails of the engine form no part of this invention they are notfurther described herein.

he connection from the carbureter 2 to the manifold 3 is through thepipe 4. This pipe is controlled by the valve 5,-see Fig.

This valve is of the butterfly type and has an arm 6 on its stem 7. Ahousing 8 is provided for this arm. I

On the top of the engine body 1 is a housing 9 for the governormechanism. This comprises a driven shaft 10 having a driven gear 11thereon meshing with the driving gear 12 on the shaft 13. This shaft 13is preferably the cam shaft of the engine but the cams are notillustrated no part of this invention.

The rear end of the shaft 10 is supported in a bearing 14 in the rearwall 15 of the housing 9, while the front end is supported in a bearing16 carried by a removable plate an opening in the front wall 18 of thehousing. so that the shaft and the parts mounted thereon may be removedthrough the opening when this plate is removed.

On the front side of the gear 11 is a bracket 19 having spaced arms 20thereon between which the arms 21 of the governor weights 22 are pivoed. These arms 21 have extensions 23 which project inwardly to engagethe ends of the thrust rods 24 which project through the gear 11 fromthe thrust sleeve 2:") by which they are carried.

The sleeve 25 carries an anti-friction thrust collar 26. Below the shaft10 is a rock shaft 27 having a pair of upwardly projecting arms 28thereon which engage the thrust collar 26 on opposite sides of thesleeve. The rock shaft 27 is carried by pivot bearings 29.

At one end of the rock shaft is an up wardly projectingarm 30 connectedto the actuating arm 31 at 32 and 33, the lower end of the actuating armhaving an offset as they form therein to position the rock shaft andbeing slotted at 34; to receive the bolt 33, thus permitting theadjustment of the actuating arm on the fixed arm 30. '7 i Y The upperend of the lever or arm 8l is connected by the link 85 to the arm 6 ofthe valve. The coiled spring 36 is secured tothe actuating arm 31 and toan adjusting tained.

scribe certain modifications adaptations to other 7 the disclosure madewill enable those skilled,

- screw 37 disposed through the front wall 9 I have not attempted oradaptations of my improvements which mightbe desirable for embodiment inother relations or engines,

in the art to which my invention relates to embody or adapt the same asmay be desired. p

7 Having thus described my invention, what- I clalm as new and desire tOSQCIII'B bYLQIr ters Patent is:

for internal combustion 1. In a governor eng nes, the combination withan mlet valve and a housing therefor, of a governor housing, a shaftprovided with a driven gear, a governor welght carrying bracket mountedon one side of saidgear, governorweights provided with arms disposedthrough said gear and pivoted on said bracket, a thrust:

on said shaft at the other sleeve mounted side of said gear and provldedwith a thrust collar, thrust rods on said thrust sleeve prosaid gearto-coact with the governor weight arms, a rock shaft having a pair ofarms spaced to embrace said thrust thrust collar, said 7 rock shaft alsohaving a rocker arm thereon,

an'actuating arm acjustably secured to said jecting through sleeve andengage said to illustrate or deas I believe 7 housing.

with said shaft and weights .are pivotally' mounted, a thrust rockerarm, an adjustable governor spring connected to said actuating arm andto said housing,-a link connecting said valve to said actuating arm, anda tubular housing for said link extending from said governor housing tosaid valve housing.

2. In a governor for internal combustion engines, the combination of ashaft provided with a driven gear, a governor weight carrying bracketmounted on one side of said gear, governor weights provided with armsdisposed through said gear and pivoted on said bracket, a thrust sleevemounted on said shaft at the other side of said gear and provided with athrust collar, thrust rods on said thrust sleeve projecting through saidgear to coact with the governor weight arms, a rock shaft having a pairof arms spaced to embrace said thrust sleeve and engage said thrustcollar, said rock shaft also having a rocker arm thereon, an actuatingarm adjustably secured to said rocker 1 arm, and an adjustable governorspring connected to said actuating arm and to said In a governor, thecombination of a shaft, governor weights, a member rotatable on whichsaid governor sleeve mounted on said shaft to be actuated by saidgovernor weights and provided with a thrust collar, a rock shaft havinga pair of .arms spaced to embrace said thrust sleeve and engage saidthrust collar, said rock shaft also having a rocker. arm, an actuatingarm adjustably connectedto said r'ockerarm, and a governor spring.connected to said actuating lever.
